Embodiments of the present invention provide a method and apparatus for sending and receiving uplink control information. The method includes: a terminal device determining a channel access type of an uplink control channel used for sending uplink control information; and performing channel detection according to the channel access type and sending the uplink control channel to a network device after detecting that the channel is idle information, or send the uplink control information to the network device without detecting the channel according to the channel access type. Therefore, in some scenarios, the uplink control information can be sent without detecting the channel, which can reduce the transmission delay and improve the transmission efficiency; while in other scenarios, the uplink control information can be sent after detecting that the channel is idle, which can avoid or reduce interference. And improve the reliability of transmission.
